The Application of RFID in Access Control Management and the Security Sector

Over the past decade, the Internet of Things (IoT) industry has experienced rapid growth. One concrete example of the usefulness of the Internet of Things is the application of Radio Frequency Identification (RFID) in access control and security management.

One of the functions of RFID in access control and security management is to quickly and simultaneously record the personal information of everyone entering and exiting.

When an authorized person carrying an RFID card or badge approaches a gate, the information on the card is automatically collected by the system without manual intervention, making access control management more practical.

In this article, we will provide further information regarding the application of RFID in access control and security management.

How Does an RFID Access Control System Work?

Before discussing how RFID is applied in various sectors, it’s helpful to understand how it works. This is the big difference between RFID and NFC. Here are the basic components that make this system function:

• RFID tag or card: This is a small chip embedded in a device to store a unique identification number.
• RFID reader: A device used to detect and communicate with RFID tags, typically installed at doors, gates, or entry points.
• Access control panel: Data from the ID tag captured by the RFID reader is sent to the controller to verify the ID.
• ID verification: A verified ID triggers a signal to unlock the door, lift the gate, or release the turnstile arm.

The entire RFID process takes less than one second. Every entry and exit is automatically recorded. This process eliminates the need for manual checks while providing a comprehensive record of who accessed which areas and when.

Application of RFID in Access Control Management

RFID access control systems cover the safety requirements of modern working environments, departmental administration, daily attendance management, and staff cafeteria or dining access.

RFID access control systems are widely used in apartments, residential areas, factory patrols, corporate research and development departments, and medical, financial, and other applications.

The following are some applications of RFID in access control management:

1. Residence / Apartment / Hotel

RFID access control systems for residential and apartment sites can effectively prevent unauthorized personnel from entering and protect the security of these sites to the greatest extent.

If an accident occurs during a certain period, information such as recorded video footage can be consulted later.

2. Office

Each employee has an RFID work card as a data carrier for attendance to realize employee attendance checking, data collection and recording, information inquiry, and attendance statistics.

Additionally, companies can use cards held by employees to manage their access to workplace information, systems, materials, and devices.

3. Hospital

Medical institutions assume the important task of providing medical care to the public. There is a large flow of people in hospitals every day, including patients, family members, and medical staff, which brings great difficulties to hospital safety management.

RFID systems can provide better and safer access control management by controlling people entering and leaving critical areas of the hospital through hierarchical authority.

Application of RFID in the Security Sector

RFID is widely used in various industrial fields, one of which is maintaining security.

RFID in the security sector has been used, among others, for parking security management, transportation systems, and asset security.

1. Parking security management

With the development of smart cities, parking difficulties have become an urgent problem to be solved, and the importance of smart parking has become more prominent.

Simply put, the so-called intelligent parking helps car drivers quickly find available parking spaces through automatic technology and provides drivers with accurate navigation routes.

In this process, a large amount of real-time data from sensors will be transmitted to a special APP installed on the driver’s handheld device.

It can be said that the establishment of an intelligent parking system brings a lot of convenience, not only reducing the time for drivers to find a parking space but also maximizing the utilization rate of parking spaces.

2. Transportation system

An important application of RFID technology in the field of intelligent transportation is automobile electronic identification, also known as electronic license plates, which is an electronic ID card formed by combining ultra-high frequency RFID technology and other related technologies.

The car electronic identification urban transportation system based on RFID technology can improve the real-time and accuracy of urban traffic management, and make urban transportation more scientific and intelligent.

The popularisation and application of car electronic identification systems can monitor urban traffic data in real time and accurately. Traffic data processed by big data can be used as data support for urban traffic congestion prediction and traffic planning.

3. Asset Security

Loss of assets, theft, and mismanagement are often major challenges that have a direct impact on a company’s operations and profits.

RFID technology emerges as a modern solution for business security, enabling real-time monitoring of assets and better protection through automated systems.
